The Dodgers optioned Outman to Triple-A Oklahoma City on Wednesday.
The return of Miguel Rojas (forearm) from the injured list will squeeze Outman off the big-league roster and back to the minor leagues. After returning to the majors in late July, the 27-year-old outfielder appeared in seven games and went just 1-for-11 with a home run and two runs scored. He will likely be on the short list for a return to the majors should the Dodgers run into depth problems in the outfield down the stretch.
